HORIZONTAL ICE-CREAM: FREEZER.

Specification of Letters Patent.

Patented July 12,1921.

Application filed March 1, 1921. Serial No. 448,807.

To all whom it may concern Be it known that I, EMERY THOMPSON, citizen of the United States, and a resident of New Rochelle, county of Vestchester, and State of New -York, have invented new and useful Improvement in Horizontal Ice- Cream Freezers, of which the following is a specification.

Heretofore, horizontal ice cream freezers have been made in large sizes with scrapers and spaddles which are horizontally disposed and great trouble has been experienced because the scrapers and spaddles have had no proper support at the front of the machine and away from the driving mechanism so that they have not functioned properly under all the conditions of service.

An object of my invention is to provide suitable support and bearing for the front ends of the scraper and spaddle so that the same will run true under all service conditions and be properly lubricated and in no way contaminate the ice cream in the freezer, and a further object is to provide a front cover which will properly reinforce the bearing and close the freezing chamber with a tight joint which will at all times be free of all contaminating matter, and a further object is to provide a structure which may be easily taken down for the purpose of cleaning the freezer. These and other objects are accomplished by my invention, one embodiment of which is hereinafter more particularly set forth.

For a more detailed description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which Figure 1 is a side elevation, partially in section, of the freezing chamber of a horizontal ice cream freezer embodying my invention.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a sectional view taken on the line 33 of Fig. 2, looking in the direction of the arrows.

Fig. 4 is a rear elevation of a bracket for supporting the front bearings of the scraper and spaddle.

Throughout the various views of the drawings, similar reference characters designate similar parts.

My improved freezer 1 is provided with the usual horizontal cylinder 2 which has at its front end an annular ring 3 with an inclined front face, as indicated at the right of Fig. 1, and this face is provided with a number of screw threaded holes that receive the cap screws 4 which, in the present embodiment of my invention, are siX in number although any suitable number may be employed, and these cap screws 4 take into resources 5 and over lugs 6 which extend radially from the periphery of the cover 7,

shown at 9 in 1* ig. 3, so as to give these lugs a slight resiliency.

This cover also carries the conventional gate 10 which is mounted in suitable slides 11 and controlled by a lever 12 in the usual manner.

The ring 3 has inwardly extending screws 13 which are two in number and diametrically opposed, one being a little above the level of the axis of the scraper and the other a little below the level of the same, and these screws 13 enter corresponding recesses in the bracket 14 which extends from one side of the ring 3 to the other and this bracket 14- is perforated at its center to receive a bushing 15 in which the end 16 of the spaddle is located and the scraper 17 is j ournaled on this spaddle and abuts against the busln ing 15,, as shown in Fig. 1. The screws 13,

the bracket 14, the bushing 15, the cover 7, the journal 16 and the scraper 17 are all arranged and disposed so as to reinforce and assist each other, the bushing 15 being placed between the journal 16 and the cover 7 and the bracket 1 L being placed between the screws 13 and the cover 7 so that when the cover is fixed by the screws a, the bracket is fixed against the screws 13 and are rigidly held in place so that all vibration and movement is impossible and the journal 16 will run free and true when in operation.

Furthermore, it is obvious that once the freezer is through its work of making ice cream, it may be readily cleansed by running hot water through the same, and if desired, from time to time, it may be further cleansed by removing the cover and taking down from it all the interior parts which may then be cleaned separately and reassembled and restored, as shown. I

While I have shown and described one embodiment of my invention, it is obvious that it is not restrictedthereto, but that it.

steady whenthe journal is revolving.

2. An ice cream freezer with lnwardly projecting lugs, a bracket resting against said lugs, a cover engaging the bracket and forcing the same against the lugs, whereby the bracket is fixed in place and a bearing in said bracket.

3. An ice cream freezer havin ra cylinder, inwardly extending lugs mounted in said cylinder, a bracket engaging said lugs, a

cover engaging said bracket and forcing the same against said lugs, a bushing in said bracket and a journal adapted to revolve in said bushing. V y

. 4. In an ice cream freezer, a cover having undercut lugs flaring from the cover and 1 extending therefrom to form slightly yielding portions and screws passing through said lugs and holding said cover to said freezer.

5. In an ice cream freezer, a cylinder containing a spaddle With a front journal, a

bracket in said cylinder supporting said front journal and a bushing mounted in said bracket and engaging said journal and supporting the same. v

(5. In an ice cream freezer, a cylinder containing a spaddle With a front journal, a bracket provided with a bushing engaging said front journal and a scraper mounted adjacent to said bushing and surrounding the journal of the spaddle. p

In testimony'whereof I have hereunto set my hand and seal this 24th day of Februa EMERY THOMPSON.
